Target Loudness
Level
Specifies the loudness level that will be targeted -40 dBEq to 0 dBEq
(
-27 dBEq
)
LC Ratio
Controls the amount of gain or attenuation that
is applied when loudness differences are
measured
0% to 100% (
90%
)
Upper Threshold
Specifies the highest measured loudness of the
input that will be permitted before attenuation
is applied
0 dB
to 20 dB
Lower Threshold
Specifies the lowest measured loudness of the
input that will be permitted before gain is
applied
-20 dB to
0 dB
Freeze Window
Specifies the size of a window in which small
loudness differences are allowed without the
need to change gain or attenuation
0.0 dB to 10.0 dB (
1.0 dB
)
Quiet Threshold
Controls the noise floor level
-80 dBEq to -20 dBEq
(
-50 dBEq
)
Attack Time
Controls how quickly the processing will respond
to sharp increases in loudness
5 ms to 150 ms (
20 ms
)
Release Time
Controls how quickly the processing will respond
to sharp decreases in loudness
20 ms to 500 ms (
120 ms
)
